SUMMARY:Foam evaluation and its applications
LOCATION:Hill Center 705
DESCRIPTION:Abstract: Foams are decorated two-dimensional CW-complexes with prescribed 
 singularities embedded in 3-space. They naturally appear in link homology a
 nd categorification. In the talk we'll explain the state sum model for foam
  evaluation that relates to both the Four-Color Theorem and a categorificat
 ion of the Kuperberg bracket (the quantum SL(3) link invariant).\n
